... is of interest due to the presence of severe pressure fluctuations at part load and of advanced blade suction-side cavitation erosion. Moreover, the turbine has a particular combination of guide vanes (20) to runner blades (15) that makes it prone to significant rotor-stator interaction (RSI...

... flow wear cavitation cavitation erosion fluid structure interaction water hammer The dynamics of bubbles in fluids have been studied for over a century. When subjected to tension, bubbles grow and subsequently collapse often, resulting in damage to adjacent surfaces. This phenomenon...

...Chen Haosheng; Li Jiang; Liu Shihan An ultrasonic vibration cavitation erosion experiment was performed to study the thermal effect during the erosion process. The ring affected zone was observed on the sample surface around the erosion pit at the incipient stage of the cavitation erosion...
